Best Electricity Tariff for EV Charging in Ireland
A dedicated EV tariff gives you a few hours of very cheap electricity overnight in exchange for a higher rate the rest of the day. If you charge an electric car at home, it is usually the single biggest saving available to you, worth roughly €700 a year against a standard day rate.
Bord Gáis Energy currently has the cheapest EV unit rate at 8.98c/kWh, Energia offers the best balance at 9.42c over four hours, and SSE Airtricity has the longest window at six hours. All rates below were verified against supplier pricing pages in August 2026.

EV electricity tariffs in Ireland compared
Ranked by unit rate. The cheapest rate is not automatically the cheapest plan: check the standing charge and make sure the window is long enough to fit the charge you actually need.
| Supplier | Plan | EV Rate | Window | kWh per Night (7.4 kW) | Cost per 100 km |
|---|---|---|---|---|---|
| Bord Gáis Energy | EV plan (Urban EV unit rate) | 8.98c/kWh | 2am–5am | ~22 kWh | €1.62 |
| Energia | EV Smart Drive | 9.42c/kWh | 2am–6am | ~30 kWh | €1.70 |
| Electric Ireland | Home Electric+ Night Boost | 10.88c/kWh | 2am–4am | ~15 kWh | €1.96 |
| Pinergy | EV Night Time (closed to new customers) | 10.89c/kWh | 2am–5am | ~22 kWh | €1.96 |
| SSE Airtricity | EV tariff | 12.13c/kWh | 11pm–5am | ~44 kWh | €2.18 |
| Standard day rate | Typical 24-hour tariff | ~35c/kWh | Any time | — | €6.30 |
| Your solar panels | Surplus solar charging | 0c/kWh | Daylight hours | Varies | €0.00 |
Rates include VAT and were verified against supplier pricing pages in August 2026. Cost per 100 km assumes 18 kWh per 100 km, typical for a mid-size EV. Suppliers change prices regularly, so confirm the current rate before switching.
How to choose an EV tariff
Work out how many kWh you actually need overnight before you chase the lowest headline rate. A 7.4 kW charger delivers about 7.4 kWh per hour, so a two-hour window tops out near 15 kWh. If you drive enough to need 30 kWh a night, a slightly higher rate over a longer window is cheaper than paying day rates for the shortfall.
Bord Gáis Energy: 8.98c/kWh
EV plan (Urban EV unit rate) · 2am–5am · standing charge: €364.89
Cheapest unit rate currently on sale, but the EV plan carries a standing charge about €120 a year above the standard smart tariff.
Energia: 9.42c/kWh
EV Smart Drive · 2am–6am · standing charge: Varies by plan
Four-hour window is the best balance of low rate and enough time to complete a full charge on most batteries.
Electric Ireland: 10.88c/kWh
Home Electric+ Night Boost · 2am–4am · standing charge: Varies by plan
Only a two-hour boost window. At 7.4 kW that is roughly 15 kWh, so larger batteries will not fill in one night.
Pinergy: 10.89c/kWh
EV Night Time (closed to new customers) · 2am–5am · standing charge: Varies by plan
Rose from 5.99c to 10.89c on 1 August 2026, an 82% increase, and was withdrawn from sale in May 2026. Comparison tables still showing 5.99c are out of date.
SSE Airtricity: 12.13c/kWh
EV tariff · 11pm–5am · standing charge: Varies by plan
Highest unit rate here, but the six-hour window is the longest available. Roughly 42 kWh per night at 7.4 kW, which suits big batteries and long commutes.
How much an EV tariff saves you
Based on 2,700 kWh of home charging a year, roughly 15,000 km at 18 kWh per 100 km, against a 35c standard day rate costing €945.
| Supplier | EV Rate | Annual Charging Cost | Saving vs Day Rate |
|---|---|---|---|
| Bord Gáis Energy | 8.98c/kWh | €242 | €703 |
| Energia | 9.42c/kWh | €254 | €691 |
| Electric Ireland | 10.88c/kWh | €294 | €651 |
| Pinergy | 10.89c/kWh | €294 | €651 |
| SSE Airtricity | 12.13c/kWh | €328 | €617 |
Savings assume all charging happens inside the cheap window. In practice most households charge some of the time at the day rate, so treat these as an upper bound. A higher standing charge on an EV plan also eats into the saving.
EV charging costs are rising
The cheap end of the EV tariff market has moved sharply against drivers. Pinergy raised its EV Night Time rate from 5.99c/kWh to 10.89c/kWh on 1 August 2026, an 82% increase affecting around 1,800 customers, having already withdrawn the tariff from sale in May 2026. The Tánaiste described the increase as “extraordinary”.
Two practical consequences. First, treat any comparison table still quoting 5.99c as out of date. Second, an EV tariff is not a decision you make once: rates and windows change, so it is worth re-checking yours each year against the table above.
If you were on the Pinergy 5.99c rate
Your overnight charging cost has roughly doubled. At 2,700 kWh a year that is about €132 extra annually. Bord Gáis at 8.98c or Energia at 9.42c are now cheaper, though you should factor in standing charges and any exit fees before switching.
EV tariffs versus charging from solar
An EV tariff and solar panels solve the same problem at different times of day. The tariff gives you cheap electricity overnight; solar gives you free electricity in daylight. They work well together, particularly if you work from home or charge at weekends, and a solar-compatible charger can prioritise surplus generation before falling back to the grid.

Solar Powered EV Charging Guide →If you export surplus solar to the grid, the rate your supplier pays matters as much as the rate it charges. Compare Clean Export Guarantee rates by supplier before you switch, since the best EV tariff and the best export rate are not always the same company.
EV electricity tariff FAQ
Which electricity provider is best for EV charging in Ireland?
Bord Gáis Energy has the cheapest EV unit rate at 8.98c/kWh from 2am to 5am, but its EV plan carries a standing charge around €120 a year higher than its standard smart tariff. Energia EV Smart Drive at 9.42c/kWh over a four-hour window from 2am to 6am is the best balance for most drivers. SSE Airtricity's six-hour window from 11pm to 5am suits high-mileage drivers and large batteries despite the higher 12.13c rate.
What is the Energia EV rate?
Energia's EV Smart Drive plan charges 9.42c/kWh between 2am and 6am. The four-hour window is the joint-longest among the cheap tariffs, delivering about 30 kWh per night on a 7.4 kW home charger, which is enough for a full charge on most EV batteries.
What are Electric Ireland's EV rates?
Electric Ireland's Home Electric+ Night Boost gives 10.88c/kWh between 2am and 4am, including VAT and a 5.5% discount. The two-hour window is the shortest of the main EV tariffs, delivering roughly 15 kWh on a 7.4 kW charger, so drivers with larger batteries or longer commutes may not complete a charge in one night.
Do I need a smart meter for an EV tariff?
Yes. Every dedicated EV tariff in Ireland requires a smart meter, because the supplier needs half-hourly readings to bill the cheap window separately. ESB Networks is rolling smart meters out nationwide and installation is free.
How much does it cost to charge an EV at home in Ireland?
On a dedicated EV tariff of about 9c/kWh, charging costs roughly €1.62 per 100 km. At a 35c standard day rate it is about €6.30 per 100 km. Over 15,000 km a year, that is the difference between roughly €245 and €945.
Why did Pinergy's EV rate increase?
Pinergy raised its EV Night Time rate from 5.99c/kWh to 10.89c/kWh on 1 August 2026, an 82% increase affecting around 1,800 customers. The supplier said the tariff had been reviewed to reflect market conditions and the cost of providing the service. It had already been withdrawn from sale in May 2026. Pinergy also cut its Clean Export Guarantee rate from 25c/kWh to 18.5c/kWh on the same date.
Is an EV tariff worth it if I do low mileage?
Not always. EV plans often carry a higher standing charge and a higher day rate in exchange for the cheap window. If you drive well under 10,000 km a year, the extra standing charge can cancel out the saving. Work out your actual annual charging in kWh and compare total cost, not just the unit rate.
Can I use an EV tariff and solar panels together?
Yes, and they complement each other well. Solar covers daytime charging for free, while the EV tariff covers overnight top-ups and winter months when solar generation is low. Check the supplier's Clean Export Guarantee rate too, since the best EV tariff and the best export rate are not always the same supplier.
